Abstract
A voltage drop compensating reactor connected between the power distribution system and the load provides a flux shifting multiple-winding reactor with a capacitor bank connected between the reactor windings. At least one line winding is oriented in a first polarity on a core, and at least one compensating winding oriented in the opposite polarity on the core and connected between the output of the first winding and the load. The opposing fluxes generated by the line winding and the compensating winding cancel and the total reactance of the device is lower than the reactance of the line winding. The input of a cross-link circuit comprising a capacitor is connected between the line winding and the compensating winding. The reactance through the cross-link circuit to the neutral (or another phase) is lower than the reactance through the line winding. Thus higher frequency currents such as harmonic currents and rf noise flow through the cross-link circuit, and are largely prevented from penetrating the power distribution system.
